Kilogram per Hour (kg/h)
Kilograms per hour are the plant-floor unit for steam generation, fuel consumption, dryer and mill capacity: a small boiler makes 1000–5000 kg/h of steam.
Symbol: kg/h
Quantity: mass flow rate ṁ
SI relation: 1 kg/h = 0.0002777777777778 kg/s (exact)
Derivation: 1 kg/h = 1/3600 kg/s.
Exact: yes, by definition
Typical uses
- Boiler steam rating (kg/h)
- Fuel consumption and specific fuel consumption
- Dryer, mill and process plant capacity
